Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the graphed function comes from:
So this is the equation of a parabola that opens upward and whose vertex lies on the point:
The graph of this function is shown below. Which is true regarding the graphed function f(x)?
- It is true that the domain is the set of all real numbers because this is a polynomial function.
- It is true that the range is the set of all real numbers such that y ≥ 5
- It is true that this parabola opens upward
- It is true that it doesn't cut the x-axis
The domain of a function is the set of values of the independent variable for which the function is defined. The square root function is defined for all non-negative real numbers. So, ...
The domain of
y = √x
is all real numbers greater than or equal to zero. (x ≥ 0)
_____
In some cases, there may be other limits on the domain of a function. A function may be defined for all values of mass, for example, but is of no practical use for values of mass greater than the mass of the known universe (or planet Earth, perhaps).
Answer:
40% apples
train going 80 miles per hour
Answer:
I'm going to assume that was supposed to be a division sign.. so 26.
Step-by-step explanation:
multiplication/division first
40/5=8
8x2=16
then addition
16+10=26
Answer:
Step-by-step explanation:
First find the slope of the line containing points (5,4) and (-7,9). To find the slope use the formula 
. Putting those values in, you have
Simplify
Then, to find the slope of the line perpendicular to that, find the negative reciprocal.
